Jay-Z and Beyoncé's twins arrived a little over a month ago, but they already share something in common with the children of another celebrity clan.

TMZ is reporting that Rumi and Sir Carter were delivered by Dr. Paul Crane, the same man who delivered Kim and Khloe Kardashian's five kids, as well as Blac Chyna and ROb Kardashian's child, Dream. Talk about needing a new catcher's mitt!

TMZ also obtained images of the birth certificates for Rumi and Sir, which nails down a firm date and time of birth: June 13th at 5:13 a.m. Rumi was the first of the two twins to get a peek at the world outside the womb.
